I installed a STS Turbo System for the 2003 to 2005 hummer H2 on my 2003 H2. The system is sold as complete, but it is missing a very important part- a one way valve. The system over pressurized my crank case leading to engine failure. The installation instructions were confusing at best and had pictures of a Vortec motor from a pickup that were labled as a H2. The instructions also stated to add a one way valve if there was no PCV valve installed on the vehicle. NO Hummer H2's 2003 to 2005 were ever fitted with a PCV valve from the factory. So much for a complete kit. Buyer beware.
